Have sort of a problem don't know how big but this occurred to me about 1.5 months ago with some hairymushroom where little by little it just died off. I was convinced that it was the RBTA which was moving around at the time and ended getting him before i got to move him. It happen again to some hardy blue mushroom. Every other mushroom are doing fine its just this one one by one there just dying off. Its placed in the sand bed and was close to the RBTA again but he would have had to move a whole lot through the sand in order to reach him which i didn't see. So what else can be causing this to happen. :'(
